The fungus candida causes a vaginal yeast infection. Your vagina naturally contains a balanced mix of yeast, including candida, and bacteria. Lactobacillus bacteria produce acid, which prevents yeast overgrowth. That balance can be disrupted and lead to a yeast infection. Too much yeast in your vagina causes vaginal itching, burning and other classic signs and symptoms of a yeast infection. Candida albicans is the most common type of fungus to cause yeast infections. Sometimes, other types of candida fungus are to blame. Common treatments usually cure a Candida albicans infection. Yeast infections caused by other types of candida fungus can be more difficult to treat, and need more aggressive therapies.

And the return of blood TO the heart has very little to do with the pressure from the heart. Contraction of muscles and one-way valves help return blood to the heart. Add: Ok, I've looked into it more because this is such an interesting question. Lets say your heart beats about 70 times per minute. That's 100800 beats per day. Your heart makes the entire blood in your body complete about 1,000 full cycles in a day. So that would mean that it takes about 100 beats to complete a full cycle. This makes sense. The American Heart Association recommends doing CPR at a rate of about 100 compressions per minute, which would mean one full cycle or blood circulating through the body.
